KX series v.1.70
CONNECTIONS - SERIAL BUS
The peripherals (keypads, expansions, sockets, etc.) are connected to the electronic board through an RS485 line, terminals A and
B. This connection complies with the generally adopted rules for this type of line. The maximum length of the entire bus section can
be up to about 1000m.
When cabling is done over large distances, over 400/500m, certain precautions must be taken:
- It is best to use twisted cables suitable for serial lines
- It is best to connect all the peripherals in cascade (with the traditional enter and exit)
- avoid making too many junctions on the line
- avoid making too many nodes or star connections with several branches
For the use of cables that also have 2 power supply conductors for the peripherals themselves, there are no special precautions. You
must keep in mind the consumption level and that the distances do not cause high voltage drops. From the peripherals you can
also supply all of the sensors connected to it with no operating problems. The bus supply terminals supply 13.8Vdc - 3A protected
by an independent, self-resetting fuse.
If connecting supplementary power supplies, remember that the negatives must always be in common and that the technical char-
acteristics must be identical to those provided by the manufacturer (see the technical data)
note: all of the devices that can be connected START WITH ADDRESS 1 (ex. keypad 1 - socket 1 - expansion 1 -
expansion 2)
CONNECTIONS - SIRENS
Terminal +C is used for lounch siren with missing positive cofiguration, when the system is ready not in alarm status, there is a
positive. When the panel go in alarm, the positive go to 0Vcc.
Terminal +PZ is used for lounch piezo siren, when the panel go in alarm in this terminal you have voltage for lounch siren.
Terminals NC - NO - COM are free exchange alarm terminals and are done using a traditional relay. (max current 2A - 30Vdc)
AP is the terminal enabled for anti-opening protection. The reference is negative. It can be configured as NORMALLY CLOSED or as
BALANCED at 1K (putting in series on the line, a resistor with that value) This parameter is found in OTHER PARAMETERS.
Note: you can also use output 1 for functions linked to the siren in order to have independent signalling of the
internal siren based on the alarm zone. Or for controlling the siren flasher with separate siren/flasher commands,
using a possible alarm log signal (function can be activated from the outputs menu).
CONNECTIONS - OUTPUTS
All outputs, except no. 2 in K8 models and no. 1 in X models, are the OPEN - COLLECTOR type, with a maximum current of 80mA.
Outputs are controlled by a traditional free exchange relay (max current 2A - 30Vdc).
For connection to the O.C. outputs, the closure is negative and the current, as mentioned above, is a maximum of 80mA. It is
therefore considered to be an open output when not closed/connected to negative. For relay connections or other types of low
absorption loads, use a positive as reference (positive supplied on the output group terminal) or any positive that has the negative
in common with the one on the control unit.
You can also use the outputs with the PULL UP resistors (value 1K) to vary the reference voltages, ex. to have positives and nega-
tives that change based on a certain programmed event.
Following are a few examples of O.C. output connections:
CONNECTIONS - LOADS
The voltage supplied is 13.8Vdc. with 500mA or 1A see the electric spcification.
